Mr. Biden was talking about the sexual misconduct allegations against Mr. Trump by several women, who came forward after a leaked 2005 recording revealed the business mogul boasting on a hot mic about using his celebrity status to get away with groping women.

“What he did and does is the textbook definition of sexual assault,” Mr. Biden told the crowd. “But it’s more than that. He said, ‘Because I’m famous, because I’m a star, because I’m a millionaire, I can do things other people can’t.’ What a disgusting assertion for anyone to make.”
